IMPROVEMENT IN AUTOMATIC SHUT-OFF ATTACHMENTS FOR WATER-CLOSETS.

Sgecification forming part of Letters Patent No. 165,209, dated July 6,1875 application file-r1 June 12, 1875.

To all whom it may concern:

Be'it known that I, JAMES CAVANAGH, of the city, county, and State ofNew York, have invented a new and Improved Automatic Shut-0ft Attachmentfor Water-Closets, of which the following is a specification:

In the accompanying drawing, Figure 1 section, of a water-closet with myimproved automat c shut-oft attachment; and Fig. 2, a detail centralsection of the water-supply cock.

Similar letters of reference indicate corresponding parts.

My invention relates to an automatic shutoff attachment forwater-closets, by which the supply of water is instantly interrupted assoon as the hinged cover of the same is released, the supply of waterregulated as desired, and by the ready access and easy lubrication ofthe parts few repairs rendered necessary.

The invention consists of the connection of the stop cock of the si11.ply-pipe by a crank lever and adjustable. rod with the hinged andweighted cover of the bowl, so that the opening of the same produces theclosing of the supply-cock, which is provided with a Wastepipe and alubricating-pipe attached by fastening-nut to the flange ot the bowl.

1n the drawing, A represents the bowl of a wa er-closet; B, thewater'supply' pipe, and (l the hinged and suitably-weighted cover. Astop-cock, D, is attached by fastening-nuts a to the supply pipe, andgoverned by a cranklever, I), applied rigidly thereto. The cranklever bis connected by a rod, d, to an arm, c, of cover 0, the lever, rod, andarm being so perforated and connected by clamp-screws that a greater orless degree of leverage is imparted to the crank b of stop-cock D, andthereby a larger or smaller quantity of water supplied to the bowl. Theadvantage-of this regulating feature consists in the possibility ofadjusting the supply of water to the closets of all the stories, so thatthe closets in the upper stories are also uniformly supplied, and not,as is commonly the case, left without Water when the lower closets arein use. When the cover is pressed down on the bowl the stop-cock isopened and the water sup- .plied to the bowl. As'soon as the cover isreleased the weight of the same carries it up and shuts the stop-cock,interrupting instantly the flow of water. The water remaining in theforward end of the supplypipe is allowed to pass off to the exit-pipe ofthe bowl by means of a waste-pipe, f, communicating by a perforation, f,of the stop-cock with the closed section of the supply-pipe O. Thestop-cock D is cast or otherwise provided with an upwardly extendingtube, g, that is attached at its narrower and threaded upper end by anut, g, to a recessed or indented part of the bowlflange, supportingthus the stop-cock, independently of the supply-pipe, and allowing, byunscrewing nuts a a and 9., the detaching of the stop-cock mechanism forrepairs. The tube 9 serves also as a chamber for the lubricant, which isadmitted through a small bottom perforation, h, to the stop-cock,securing thereby the regular working of the shutoff attachment for aconsiderable length of time without re-oiling and repairing. The shutotfattachment may also be used with the common pull-lever in place of theswinging cover, and applied to any water-closet.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. An automatic shut-off attachment forwater-closets, consisting of a water-supply pipe, with regulatingstop-cock, connected by adjust-able lever mechanism with the hinged andweighted cover that operates thereby the stopcock, substantially in themanner and for the purpose set forth.

2. The combination of the stopcock by a supporting-tube andfastening-nut with the flange of the bowl, to be readily detached forrepairs, substantially as specified.

3. The.supporting tube ot' the stopcock, forming a lubricating-chamber,and having bottom aperture to supply oil to stopcock, substantially inthe manner set forth.
